4) We all know that in space no-one can hear you scream. However, in water, sound actually travels four times faster than in air, due to the proximity of the water particles transferring the vibration at a more rapid rate.

6) “I’ll be just a moment” is a common expression in everyday life, but how long actually is an elusive “moment”?
